The quills enter the surface of a rubber or other elastic lift to be attached, and compress the material over the area therein through which the attach 'Fig- l‘shdws in Side elevatiqn with elements in section, portions of aheel-attaching machine with .55 ing iasteninss ‘are tore driven.

This lower arm rests up on the head of the screw, and, in turn, supports mechanism M, and into the heel-seat of a shoe which is pressed against the base by a vertically reciprocable jack (not illustrated) and upon which it is supported. the upper arm which moves in contact with it at the point of intersection of the arms. The The fastenings are preferably arms of each pair are geared at 1B or 19' to os out from strings of ?ber F~(Fig. 1), delivered cillate together, and the approach ofv their for ward ends under the influence of a tension spring 18 or 18’ connecting them is adjustably through tubes 26 terminating in a foot-plate 28, and severed by a loader-block 30 having a com pound movement of translation and oscillation. lo limited by a stop-screw 80 or 80' threaded hori Actuated by mechanism 32 (Fig. 4), the loader zontally through one and engaging the other. block delivers the cut fastenings to the die-block passages 14. The insertion of the fastenings in For contact with a periphery of a lift inserted be the work is effected by a gang of drivers 34, which ' I is located upon their inner edges in front of the may first act as awls, as in the previously men tioned La Chapelle patent. These drivers are ?xed in a plate 36 carried by a top-girt-38 upon side rods 40, 49 reciprocating vertically in the frame It. The plate 36 is separably mounted in opposite ways 42 upon the top-girt, it being “ latched by a spring-plunger 44 movable in said top-girt and received in a depression in the edge of the plate. The gang of drivers operates in the corresponding group of multiple die-passages 14, it ‘being changed together with the quill-plate l8 as the inserting design varies.‘ The side rods 40 areactuated from power mechanism through a clutch (not shown). , 7 Considering now the features peculiar to this invention, the mechanism M includes a heel base-holder m and a top-lift-holder m’ (Figs. 5, 6, 11 and 12). The respective holders have car rier members 50, 50’, each of which is of L-shape and has an arm 52 or 52', extending from front to rear of the machine, from the rear‘ extremity of ; whichprojects a transverse arm '54 or 54’. The arms 52 and 52’ of the two holders lie at opposite sides of the die-‘blockrl2, while the arms 54 and 54' are superposed, thearm 54’ of the holder m’ being uppermost. They are adjustable fore and ‘ a aft by virtue of their support upon the heads of screws 56 or 56’, threaded vertically into the un derside of the die-block and passing through slots 58'or 58' extending longitudinally of the carrier arms 52. One of the rear screws 56" at the op posite ends of the transverse arms 54 and 54’ may be common to the two‘ carriers, through openings 58" in which they pass. To vary the position of the holders, the forward extremity of each of ‘the arms 52 and 52' has a depression 60 or 60’ in which lies a collar 62 or 62’ upon a screw 64 or 64', threaded horizontally into the front of the die-block and rotatable by a head 66 or 66'. With the screws 56 and 56’ loosened, either of the screws 64 or 64’ may be turned by its head situ ated conveniently for the operator at the front of the machine, and the holders m. and m’ brought to the correct relation to each other and to the passages in the die-block for the particular inserting design in use. In this adjusted posi tion,‘the carriers may again be locked by tight tween the arms of the holder m’ (Fig. 11) , there , ‘ intersection of said arms opposite projections 82, 82, while at their forward extremities are rotat ‘ able about vertical axes rolls 84, 84 having re duced peripheral portions (Fig. 3). Upon the arms of the base-holder m (Fig. 6) are similar ly situated rear contact members 88, 88 and for ward contact members 90, 90. These are shown as levers fulcrumed at92 beneath the arms and each urged normally down at its inner end by an expansion-spring 94 interposed between it and the arm upon the inner side of the fulcrum. The contact of the outer end of the lever with the arm determines its normal ‘angular position. As in dicated at 96 in dash-lines in Fig. 6, contact-rolls may be placed upon the inner ends of the levers 96, if this be desirable. In applying heel-parts to'the holders 1n and m’, the operator presses a lift T between the rolls 84, the arms 12 of the holder mf yielding against their spring 18' tov admit the lift and the rotation of the rolls facilitating the inward movement. This continues until the rear of the lift at the opposite sides of the longitudinal axis strikes the arm-projections 82. These furnish a back-stop which determines the position of the lift along this longitudinalaxis. ' As the operator frees the lift, the pressure of the rolls against the opposite sides betweenthe breast and the center will turn said lift about a vertical axis, if it is not already symmetrically located, until the longitudinal axis . is centralized with'respect to the passages I4 in the die-block I 2 and its quills 24. In this rotation of lift,‘ it remains in engagement with the pro jections 82, so its position from front to rear of the die-block is determined. A heel-base H is similarly inserted between the arms of the holder m against the levers 88, the unfinished periphery projecting beneath the reduced peripheries of the rolls 84 and is turned by the contact of the inner ends of the levers 90 or the rolls 96 upon them, its correct location both longitudinally and angular ly ‘being attained in the same manner as the lift T. Were it necesary to insert the lifts into the holder m’ in contact with the ends of the spaced quills 24, there would tend to be interference with the movement. ~ To prevent this, the lower por ening the screws 56 and 56'.‘ Each of the car rier-arms 54 and .54’ is depressed between its ex tions of the quills are shrouded by guard-plate tremes to receive a pair of locating and grasping arms for heel-parts, those'for the base-holder m underside of the. quill-plate I 8 (Fig. 3), it be I00. This plate is movable in a recess at the ing , held against ‘downward displacement by being designated as 10, 10 and those for the the headsof screws I02, which extend through lift-holders m’ as 12, 12. The arms of the pairs openings in the , quill-‘plate and are threaded 10 and 12 are pivoted separately at 14 and 14', ‘vertically into the guard-plate,“ In the guard respectively, upon-the arms 54 and 54' of their‘ vplate is an opening 104 for the reception carriers and cross each other from the pivots to o‘o'f'each quillf the lower end of which lies their" forward heel-part-engaging portions. Each of the pairs of arms 10 and 12 are given support against downward de?ection by a screw 68 or 68', threaded upwardly into the arm 52 or 52' 0f the corresponding carrier 50'or 50" and normally above the lower? surface of the plate (Fig. 3). In its lowered position, the guard-plate is yieldably maintained by expansionrsprings I96 "having their opposite extremities seated infre c'esse's in the quill-plate and guard-plate. 'The 2,408,844 underface of the guard-plate presents a surface free from interfering projections when the top lifts are slid into place ‘in the holder m’. Yet, when clamping pressure goes upon the work (Fig. 10), as a result ‘Of the elevation of theshoe supporting jack in preparation for the insertion of the fastenings by the drivers 34, the guard plate yields freely, so the quills will enter the 6 the head of the plunger and hold the door against closing.

These depressions are in vertical the pinion holds the locking slide at its extreme H5 (Figs. 1, 4 and 5), which is adjustably at registration for each matching pair of platesand are differently arranged in each pair transversely of the machine for all the inserting designs. When the operator must change the position of the driven fastenings because of the differing I character of the work, he adjusts the matching bar in one or the other of the slots I26, until it will enter the vertically alined depressions I24, I26. Consequently, when the doorv can be closed, it follows that the driver-plate'and quill-plate supplied will co-operate correctly, if each is fully in place and latched by the respective plungers 44. and 22.

This locks the hand-lever against actuation so, if the clo sure of the door is prevented by mismatched fastening-inserting elements or by their improper location, starting of the machine is impossible.
